30.07.2008: Levers and motor
Test motor and inspect the lever. In my case the lever was broken at the point where it connects to the shaft operating the flaps. A new lever (left) was $16 at the dealer (part 5334693). I had to transfer the little rod socket to the new lever. Apply some grease on the outer surface.

Air distribution motor and lever replacement on a 1999 Saab 9-5. The climate control system in the car operates a large air distribution flap, which directs the air to the dashboard vents, defrost vents or the floor.

When the system detects a problem with the air distribution flap, it sets error code 12 (motor short or open circuit) or 13 (flap jammed) at ACC calibration. Most of the time it's the motor itself or the plastic lever connecting it to the shaft. This article shows how to remove and replace both. You need to re-calibrate the ACC by pressing AUTO+OFF after the work is done.

Tools:

Torx T25 screwdriver: glovebox screws;
Phillips screwdriver or 8mm socket: stepping motor screws;
needle-nose pliers: testing the shaft.
